Websocket communication for Individual Device - Need Solution

We are building a search engine for vehicles using Python rest-framework and Angular 8

When I call the web socket API,

ws://localhost:8082/api/socket?token=<MyTOKEN>

It works fine and and receiving messages from the server successfully. The message contains all the devices and positions of the respective user account.

I want to show the realtime tracking to the public.
When an anonymous user visited our landing Page, we have to establish a websocket communication for a particular device. So the traccar server has to send the positions and attributes of a particular device. We do not need all the device positions. Because our account(s) might have more than 1000 vehicles/devices.

Please suggest the solution.
